Acoustic Emission Produced During Heating of Tin and Zinc Single Crystals

CODEN: JTEVAB

Abstract

Acoustic emission activity has been detected during heating of tin (Sn) and zinc (Zn) single crystals from 0 to 130°C. The emission of Sn occurs copiously only if the heating starts below a temperature of about 18°C, and lasts up to a higher temperature between 60 and 80°C. The results may be interpreted by relating acoustic emission to processes in the α ↔ β phase transformation. Although still qualitative, such a hypothesis permits us to have useful information on the nucleation time of the α-phase and on the temperature hysteresis of the transformation.
